Fernando Alonso says he is 'not too worried' about the pace of the Red Bull machines after Sebastian Vettel and Mark Webber stormed to a dominant 1-2 finish at the Malaysian Grand Prix.

Alonso struggled throughout Sunday's race with persistent gearbox issues before retiring two laps from the end.

"They have three pole positions, but the three wins I'm not sure, because we were very quick in Bahrain and we were maybe quicker than them in Australia," said Alonso. "Here it was a strange race, too easy for them because we made a mistake in qualifying. We are not too worried at the moment.

"As always you need the consistency to be Champion, but also you need to be fast. We are only in the third race so it's normal that the leader changes in the first races. You need a few races to settle down the Championship."

Alonso now lies joint second in the championship standings with Sebastian Vettel after team-mate Felipe Massa's seventh place was enough for him to take a two point advantage.

"As usual, you need to finish all the races if possible and to take points, but also especially with the news points system you need to win races as well, because it's a good reward of 25 points. At the moment it's open with many drivers around 30 points. But as I said, when the Championship goes to the end I'm sure only two or three drivers will fight for it.

"It's a very long championship and we are capable of improving the car a lot. We know in which areas we need to improve the car, so I'm more or less confident that we can have the best car in the next few races."
